Kyrgyzstan's interim government on Wednesday announced that its leader Roza Otunbayeva will serve as president until the end of 2011.

The term of the new president, who came to power on April 7 after the ouster of former President Kurmanbek Bakiyev, will last until Dec. 31, 2011, the government said in a statement.

Meanwhile, the government said that Otunbayeva, a 59-year-old former diplomat, will not be entitled to run in the presidential election planned for 2011 and that the country will hold a referendum on changing its constitution on June 27.

Earlier on Wednesday, the interim government declared a state of emergency in the troubled southern city of Jalalabad in an attempt to curb violent local clashes.

A curfew was to be imposed every night during the special period lasting until June 1, according to a statement from the interim government, which said the measure was aimed to ensure the security of citizens and an early return to public order.

The move came on the heels of fresh clashes between Bakiyev supporters and security forces loyal to the newly established interim government. The latest violence left two people dead and dozens of others injured.

The Central Asian country has been plagued with unrest since Bakiyev's departure. The ongoing violence has claimed around 100 lives and left over 1,500 injured.
